is it just me but i think my S3 screen is too vivid in color?? too much red (i notice on actors face), green and blue specially when watching 720P or normal 480P rip movies??
im using 404 V70 rom from wild if it matters..
No its not just you. Im using stock at&t s3 and colors are just too vivid, like you said. Especially red. Display on my i777 was much nicer.
If you are on stock LH2, you can install Morfic's kernel and change the gamma hacks to hue your colors towards more R,G, or B. Obviously, you need to be rooted and know how to install kernels and such.
Much the same as with Voodoo kernels on earlier Galaxy devices.

ThanKs. not sure if my rom will do this though (xquizit v70) but im surprise with so many roms, dev, fix and hacks here that no one made a universal fix yet?? It's really not that good watching movies on the s3 specially if the scenes are with many red blue colors... Even just looking at photos too? Colors are just too dark...
hoping wildchld is reading this and maybe incorporate the fix to his rom..
I would kinda like Samsung to take action and come up with a fix in their JB update..
It'd be hard to fix, my screen is perfect.. They could add sliders and settings though. Kind of odd my tv and monitor let me adjust but my phone doesn't.

Does it correct the colors on its own or is there a setting that comes with the kernel that you can adjust yourself?
That's just the nature of superAMOLED.

Hi Galaxy S II users and developers!
I'm working since months on Galaxy S II Super AMOLED+ screen calibration and rendering customization.
As it takes a lot of time to get something really usable, I decided to publish dev snapshots as a free application on android market.
This project takes so much time because I reverse-engineer all the mDNIe image converter registers one by one. Same for the ld9040 Super AMOLED+ controller.
Then I measure the potential effect of settings found, transform it into comprehensive settings etc.
I also back-up all this by measurements made with a calibrator.
Most of this reverse-engineering will be published as GPL source code.
I don't provide any kind of support for the dev snapshots but I'm sure you'll be interested discussing screen stuff here.
Icon chose is self-explanatory: unstable software!
I have ambitious plans for this application. It may become more powerful than anything you saw before affecting screen rendering on any mobile device
I've installed the Market version but can't see differences between the Native and Samsung mode.
Same as with the earlier version you distributed on Twitter. I've read there you said it worked only on your SGS2. I guess it has been fixed now but still, no changes for me.
EDIT: I see a change now between the 2 modes, my screen mode was set to Movie, not Standard. And I remember having seen in the app you change the Standard mode settings only. Maybe worth adding it to the 1st post?
I was also using the movie mode but sometimes the screen will became a little bit greenish.
I'm so happy with the screen Turner now especially with light blue!

exciting only things i hate after switching to sgs2 (from i9000) was color calibration (and banding issue) and a bit sound quality which can be increased even though its not that much difference..
@supercurio do you have something in mind about color banding or its just calibration?
Nice start supercurio!! Happy to know you have started working All the best
thanks for the early feedback:
@snark_be as its really dev snapshots, I won't document it as virtually anything can change from one day to another.
Thats why sharing your observation with other curious experimental testers is so valuable
As someone stated before, I got good result against light blue colours...

Color banding: mostly done already.
Disabling artificial sharpening on everything make any banding very hard to notice.
Still, some apps are runing in 16-bit mode without dithering on MALI GPU instead of 32bit as you can see in Angry Birds RIO introduction animation.
Samsung settings apply sharpening even on dithered images. Result is not good, as expected.
The gradient pattern in today's app show that.
Gradient itself is a screen screenshot of Samsung browser rendering, for an accurate simulation.
The app will be declined for power-users, allowing full control over all the settings.
Sharpening, color saturation or tones: its all a matter of user preferences.
For Calibration I'll work on linear domain, directly tuning AMOLED hardware and not mDNIe effect.
Its what allows the best precision and avoid ending with 7 or 6bit usable per channel, but due to how is supposed to work factory calibration it's also the only way to fix color calibration issues, that makes some screen very different from others in terms of white balance, especially in low brightness modes.
hi
i tried tune it but it doesnt work.
When you look at letters ex web you see bluring letters. I discovered i had the same problem on windows 7 but switch of smooth edges of screen font and font are sharp crisp. Take a look http://forum.xda-developers.com/showthread.php?p=15554743#post15554743.

Yes, everyone eyes gets lazy when used to a sharpened result.
Immediate comparison makes the normal rendering looks blurry even if it's not − brain trick!

Maybe you just don't like Android font hinting.
Personally I prefer stronger hinting like freetype "Best Contrast" one available on Linux desktops.
Issue with this kind of string hinting is that it doesn't play well with arbitrary font size.
Shapes become 1px or 2px wide but nothing in between, probably why Android uses an intermediate hinting, that eventually works better on higher density screens.
does this only work on stock based rom? are you planning to get this working on cm based rom as well?

It will work on CM based ROM when they'll re-add mDNIe support in their kernel.
mDNIe feature doesn't depend on kernel patches as Samsung nicely allowed customization in their own driver.
Of course this official driver must be enabled (CM) and not destroyed in its functionality (hardcore's patches)
I discussed it with Unhelpful and codeworks a few days ago and will contribute if needed.
Edit : seems to work, even though difference barely is noticeable, I guess it'll improve with updates
this may be a solution of fixing the left side yellow tinted screen just like mine
WOW~~supercurio you are come back again~welcome! just installed it from market~
native mode seem look soft and warm ..i like it..
samsung mode look dazzling and cold..
but i think it's a long way to go...
but i am very happy..you are back...
because i love your voodoo lagfix voodoo color voodoo sound for SGS..
also hope you can bring some things for SGS2~~
Says this device is not supported, running CyanogenMOD7 ver 31
Incredible difference. I really hated the sharpening Samsung do. Cannot thank you more for your hard time put into this.
This has potential to be a major breakthrough for SGS2 phones. Modifying our displays to fit everyone's needs is a much needed addon.
Thanks Supercurio!
Ive read that the One X tends to run a lot brighter for the equivalent setting on phones like the SII.
Is it possible to tune the brightness level that the Auto setting provides, and the external light at which it "ups" the brightness - as in my opinion, HTC's setting, although wonderful, is overkill in many situations, and screen on time needs all the help it can get.
Cheers.

if things aren't changed in ICS, you can decompile the /system/framework/framework-res.apk and then edit some xml's in it. Compile it again with the modified xml's and at last adb push it into the system partition. and this procedure requires a unlocked system partition.
if you don't want to unlock / don't know how to edit the stuff, the most feasible way is to put a brightness widget on homescreen and change it manually.

leedroid, insertcoin and a few of the other roms here have the option to lower the brightness in their tweak settings. If you search for it, j4n87 also created a flashable xml mod that lowers the brightness as well.
Cheers, I saw one on XDA for what I thought was the One S but it must be what youve just mentioned above I think.

Yes, we're on the same page although I don't understand italian . The mods I'm referring to all alter the baseline brightness as opposed to just the regular screen brightness based on ambient levels.
I'm running CM9 which allows you to edit baselines for screen and softkeys, but the roms and mods I referred you to do the same thing with less granular control. j4n87's mod is pretty dim but worked well for me until I switched to CM9. You could always crack open his zip and change the levels yourself before flashing.
Here is the link:
http://forum.xda-developers.com/showthread.php?t=1595559
Yeh haha I don't speak Italian either just stumbled upon that on featured videos! Erm I knew CM9 had it working, can you point me in the direction of the best build? I need HDMI out but can live without Hotspot (which I believe is the only problem causer?). What's CM9 battery overall before these screen modifications?
I've tried about 6-7 of the roms here, they're all pretty much the same with varying levels of tweaks. I'm pretty sure that HDMI is working on the majority of them.
I love the hardware on this phone but not fond of Sense at all. Looking forward to more AOSP/AOKP based roms. The only available CM9 rom still has some bugs that need to be addressed (Phone, GPS, Camera - all working but with flaws) Battery life is excellent though I'm getting 4.5-5+ hours of screen on with heavy to moderate use using Faux123's kernel.
Is that the CM9 over at Modaco? Or is there an active one here?
That's great screen on time by the way.
Ideally I want one based on CM9 but with the sense Camera, that's all I can see thats worth keeping. Sense just isn't worth the performance hit IMO. It looks pretty cheap, especially with all the colourful busy icons...
Yes I'm using the build from modaco, jdroid is apparently working on a AOSP version and is beta testing. He said that they may release something this week.
How are you finding Screen on times for video playback/streaming by any chance?
Also, have you tried to see if the force dual core app helps?
Ill know myself tomorrow, the phone arrives...!
Iv been complaining about my battery life on various threads (its 7hrs Max... Minimal use). I keep my brightness at 60% otherwise I get yellow tints.
Ive been told to install a custom rom to hopefully save battery and adjust the colors to remove that yellow tints.
Im using Apex right now. I dont see an option to adjust colors.
Suggestions?
Some AOSP ROMs and CM9 have the option. Hope that helps!

I think every rom has them at this stage.
If you use franco kernel the controls for the colours for his kernel are in his app.
Thanks. I saw the GlaDOS kernel (love the name). And I was going to try that with its app but its not free.
Ill try your suggestions. I was just curious if any one rom over others had better battery life then expected.
Franco's app isn't free either but its only like 2 dollars. That's nothing.
Some rooms have colour control built in like cm9
I recently acquired a galaxy nexus. It has a slight purple tint at like under 15%, and a huge one at exactly 0%. Is there a way to adjust the colors so I can get rid of/minimize the effect. Also is there a rom that looks exactly like the stock or something. I am pretty nooby at this. What is the best kernel?
Most kernels allow you to change your color settings, but I suggest you try Franco's App in the Play Store and download either his stable or exp version of his kernel, and then adjust settings in the "color control" settings area.
All of our kernels will allow you to change the color settings and most of them have apps. All of the roms look like stock as well except paranoid android and slim ICS. Kernels are good and bad for everyone and what works for one person will not always work for another. You should try them out to see how your phone responds to them.

Do I have to make a back up? And how would I go about doing that?

Yes, you will have to make a backup.
Then just download the kernel and flash it via ClockworkMod Recovery.
Also, the kernel control apps do cost a small bit.

Is the purple thing fixable via color control? Because at about 15% most purple goes away but if you look at gray under the notification center there's still purple.
Purple tint may be fixable with color control.
You'll have to play with the values, but I'm sure you can get a set-up that suits you.
Secondly, use my sig to get you up to speed on installing all of this if need-be.
Do I flash rom before kernel? Or vice versa?
Rom then Kernel yes.
Download AOKP. I know they have a working color control built in.
Or if you done want to change roms. Download the Franco.Kernel updater app.
It has a wonderful color control that I use all day depending on lighting.
What's the difference between Franco color control and AOKP color control?

They are the same really. But the app has a better layout and it works on ALL roms.
Also if u change the kernel on AOKP it won't work anymore.
I'll tell u how to get the Franco.kernel updater app in a PM. Okay???

If I flash Kernel and Rom, can I still exchange my device if I'm not satisfied?
YES.
But make sure you unroot. Use wug's toolkit to do that.
Guys, I just flashed AOKP and noticed the purple is gone. Should I still flash franco for better battery life?
It's not a secret that AMOLED screens like the one installed in S4 mini have wider color range than IPS what often results in over-saturated images which were prepared for standard sRGB range.
Stock S4 mini ROM has means to change color profiles. So the question is - if this functionality also included/planned to be included in S4 mini's CM and kernel CM uses for this model? Could profiles be anyhow adjusted?
It's on my to-do list.
Really glad to hear it, Arco! Thanks!
Could you please share a bit about mechanism behind that? Is it really some driver/kernel-space functionality or it is being implemented on higher levels?

Haven't really looked at it yet, but I think both kernel and user space changes are needed.

Hi arco68,
I'm also interested in a solution for the over-saturation problem of the amoled of my S4 mini. Before that I'll keep my stock rom that has the profiles included.
In the meanwhile any progress on that?
S4 Mini oversatured display - solution!
Finally I found something that really works: S4minisettings.apk

look for F4k's post
This build is for cm 11 (4.4 kitkat). The only thing is you have to manually put it to system/apps/ folder and then correct the permissions to
rw,r,r (644)
otherwise it doesn't work.
To get really natural colors instead of the oversatured ones you have to set mode to "natural" and temperature to "normal". Sometimes you have to switch the display off and on to get the settings applied.
Great thanks to F4k!
Cool!
Finally i get rid of this unnatural colours,
thanks peter and f4k! :good::good::good:
